Is It a Heart Attack or Angina?

It’s dramatic when someone has a heart attack on television or in the movies. But in real life, symptoms can be more subtle and difficult to identify. And because heart attack and angina symptoms are so similar, it may be hard to tell what's going on. But knowing the differences -- and the reasons behind them -- can result in seeking treatment sooner, and living longer.

  • Shortness of breath with exertion, which may later develop into shortness of breath at rest and at night.
  • Fatigue and weakness.
  • Fluid buildup in the legs and feet.
  • Heart palpitations, if atrial fibrillation develops.

Chronic mitral valve regurgitation

Primary MR. If you have mild-to-moderate primary MR, you may not have symptoms. If you have severe disease, you may have symptoms when you are active. Symptoms include:

  • Fatigue and weakness.
  • Shortness of breath.

Secondary MR. If you have secondary MR, you likely have symptoms of the heart problem that has led to the regurgitation. You may have symptoms of heart failure or coronary artery disease.

Acute mitral valve regurgitation

Acute mitral valve regurgitation is an emergency. Symptoms of acute mitral valve regurgitation appear suddenly. Most people who develop acute MR are already in the hospital or emergency room because of another heart problem. Symptoms include severe shortness of breath, fast heart rate, lightheadedness, weakness, confusion, and chest pain.
